But it is also a good idea to get a backup when you make any other change in the webUI since all webUI settings are saved to flash. When it has finished clearing it will let you format the old parity as a new data disk. Wait until then to make the backup. Then the backup will know that disk is now a data disk and not parity. Old 2TB parity drive is now cleared and formatted. And I just did a backup of the flash drive. Again, thanks for the tip By the way, the 2TB drive was formatted in xfs, while all my other drives are reiserfs Is this OK? Quote Link to comment

No, but not for the reason you think. Mixing format types in the array is perfectly fine. Using reiserfs is not recommended. I suggest you use the newly added XFS drive to migrate your other drives to XFS. Copy all of one of your other reiserfs 2TB drives to the XFS drive, when you are sure the copy is complete and verified, change the file type of the source to XFS, and format it. Do that one at a time until all your drives are XFS. Quote Link to comment
French-Guy Posted November 21, 2018 Author Share Posted November 21, 2018 So I should copy the content of drive #1 to the newly formatted XFS drive, check everything is fine, then format drive #1 into XFS, and copy back data onto it And do this for all other drives Is that correct? How do I copy from 1 drive to another one actually? Thanks Quote Link to comment

Which specific drive the data is on doesn't matter for user shares. Some light reading for your enjoyment. 🤣 https://wiki.unraid.net/File_System_Conversion Quote Link to comment
French-Guy Posted November 21, 2018 Author Share Posted November 21, 2018 But i have 3 x 1,5TB and 1 x 2TB data drives.... So if I use the old parity drive (2TB - xfs) as a temporary drive to empty each drive and format them as xfs, don't i need to coy back the content of each drive before doing the same for the next one?

JonathanM Posted November 21, 2018 Share Posted November 21, 2018 Just use the freshly formatted XFS drive as the destination for the next reiserfs victim in line. D1-2TB rfs copy to D5-2TB XFS format D1 to XFS D2-1.5TB rfs copy to D1-2TB XFS format D2 to XFS D3-1.5TB rfs copy to D2-1.5TB XFS format D3 to XFS D4-1.5TB rfs copy to D3-1.5TB XFS format D4 to XFS Done! End result, empty 1.5TB XFS in slot 4, all your data in slots 1,2,3,5. If that arrangement bothers you, after you finish the migration you can set a new config and assign the drives with the old parity in D5 as D1 and the rest of the drives down a slot number. Since you only have 1 parity drive, parity is still valid and if you select the "parity is valid" you will be fine. Quote Link to comment
French-Guy Posted November 21, 2018 Author Share Posted November 21, 2018 It's clear, thank you.......I don't think this new arrangement will bother me at all One more question though: how do I copy from 1 disk to another one? Is it done thru the GUI? Do i need a specific plugin? Quote Link to comment

Either command line rsync at the local console or ssh /telnet with screen, or the unbalance plugin. There are more ways to accomplish it, but those are probably the most efficient.

French-Guy Posted November 21, 2018 Author Share Posted November 21, 2018 OK, I will have to look at how the unBALANCE plugin works exactly.... Thanks for all your support Quote Link to comment
French-Guy Posted November 21, 2018 Author Share Posted November 21, 2018 (edited) OK, so do I just select "from" (D4-2TB and select all the shares) and then select "to" (D5-2TB), then click on Plan? And if there is no issue detected, I can unselect "dry run" and click on "Move"? Edited November 21, 2018 by French-Guy Quote Link to comment
JonathanM Posted November 22, 2018 Share Posted November 22, 2018 You can move if you wish, but I prefer copy as it's much faster, and you are going to be totally erasing the source drive by formatting it anyway. Just make sure there are no docker or network writes to the drives you are operating on. Reads are fine, but will slow the process a little. Quote Link to comment
French-Guy Posted November 22, 2018 Author Share Posted November 22, 2018 ok, so let's go with a "copy" then.....I'll keep you posted Thanks Quote Link to comment

French-Guy Posted November 22, 2018 Author Share Posted November 22, 2018 Good morning.............................5 hours before completion 😕 You said "Copy" was much faster? I can't imagine if I had selected "Move" Unless I have a problem somewhere??? Quote Link to comment

French-Guy Posted November 22, 2018 Author Share Posted November 22, 2018 i see both data drives are blinking, but also the parity drive Does the parity drive need to be involved during the copy, or could it be "deactivated" to do the copy faster? Quote Link to comment

Unraid parity is realtime and all write operations (write, delete, format are all write operations) update parity simultaneously. This is why Unraid writes slower than the speed of a simple disk write. It would be possible to remove parity and then rebuild parity afterwards, but that isn't really going to buy you much because then you have to wait for parity to completely rebuild. Large volumes of data just take a while even if things are working correctly. And as mentioned, without diagnostics, we can't say for sure if things are working correctly. Quote Link to comment
French-Guy Posted November 22, 2018 Author Share Posted November 22, 2018 ok, will post a diagnostic when copy is completed...... Quote Link to comment
trurl Posted November 22, 2018 Share Posted November 22, 2018 5 minutes ago, French-Guy said: ok, will post a diagnostic when copy is completed...... Diagnostic won't slow anything down. And the reason for asking for one is to see if there is anything affecting copy speed. Or you could just take a look at the log in the webUI and see if you see any disk connection issues.

trurl Posted November 22, 2018 Share Posted November 22, 2018 So, looks like this is the first diagnostic you have posted to this thread. There isn't anything in the syslog about any errors but SMART for 3 of your disks are reason for concern. When you look at the Error column in Main - Array Devices are they all zero? When you look at the Dashboard, are you getting any warning indicator for any of your disks? I suspect you do have warnings on some disks in the Dashboard. You really should have addressed these before anything else you were doing in this thread. Do you have Notifications setup to alert you immediately by email or other agent when you have any issues? Relevant SMART for these disks: Disk2, this attribute isn't normally monitored by Unraid, but it says FAILING NOW Serial Number: 6XW0Y8ZN ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 184 End-to-End_Error -O--CK 001 001 099 NOW 112 Disk3, not sure if attribute 200 is important for this model or not Serial Number: WD-WCAVY0146918 ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 197 Current_Pending_Sector -O--CK 200 200 000 - 128 198 Offline_Uncorrectable ----CK 200 200 000 - 16 200 Multi_Zone_Error_Rate ---R-- 200 166 000 - 155 Disk 4 Serial Number: WD-WCAZAH561359 ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 5 Reallocated_Sector_Ct PO--CK 200 200 140 - 13 196 Reallocated_Event_Count -O--CK 187 187 000 - 13 Not sure which should be the first to be replaced. I am guessing disk3 but I'm not sure how serious disk2 is. I wouldn't keep any of these in my array. Quote Link to comment
